Batch Upload

By default the Upload initiates a separate POST request for each selected file. To alter this behavior use the batch option of the component. When set to true, all files selected at once, will be listed as a single item in the files list and will be uploaded in a single POST request.

    [batch]="true">

  `
})

  uploadSaveUrl = 'saveUrl'; // should represent an actual API endpoint
  uploadRemoveUrl = 'removeUrl'; // should represent an actual API endpoint
